Hypertech42500 Max Energy Power Programmer

Works as advertised. Shift points are perfect now. Level 2 produces a lot more power and driveability is so much nicer. Had to manually enter my VIN for some reason but no sweat.

Fellow 7.3 owners, you know the deal: for all of the many, many outstanding features of these old workhorses, 0-60 time is not one of them.If you are like me, then you're probably tired of getting smoked off the line by bikes.And by bikes, I mean bicycles.I'm talking about "oomph". "Pep". "Get up and go". Whatever you call it, the stock setup for a 7.3 just doesn't have it. To clarify, this isn't talking about being able to burn out, or trying to be one of the cool kids... this is wanting to not have to absolutely floor it when the light turns green.I've known about these kinds of tuners for a while, but I was hesitant... they aren't exactly cheap, plus I just could imagine myself with a flashlight with my head under the dash with a bundle of unhooked wires and my alarm going off just beyond confused. An unappealing situation, to say the least.That is, until a couple weeks ago, by a stroke of luck I met a fellow 7.3 owner at the grocery store, and he had one of these tuners and I was shocked how easy it was! No chips, no wires, no splicing or electrical tape or frustration... just plug it into your OBD port and follow the instructions.Not only does it give you 3 different stages of performance, it also gives you the ability to read/clear your DTC codes. The final selling point for me was also having the ability to input your tire size... I had put larger tires on my truck, which unfortunately messes up the accuracy of your speedometer due to the various variables the computer uses to calculate speed/mileage. Thanks to this tuner, it reads correctly again!I can't say enough good things about this tuner... even just going from stock to Stage 1 is a massive difference. You will be shocked at how much life these breathe into the old dog! Now chances are that you will have to update the tuner prior to being able to use it, but that's as simple as plugging it into your WINDOWS computer and following the instructions.To wrap up, I give this product two thumbs up! It's easy to use, fairly priced (compared to some of the others out there) and once you see just how much of a difference it makes you will be wondering why you didn't do it sooner! No more sluggin' along for you, so what are you waiting for?? Do it!Do it.

Very easy to use and the results where better than expected and yes I would definitely buy hypertech products again

I have to admit I was skeptical ordering this product but I took a chance because of the majority of good reviews. I bought an older truck but new to me and it did not have quite enough power for me so I thought I would give this a shot. My truck is a 2001 f150 with a 5.4 V8. Within 20 minutes of plugging it into my truck and going through the set up I was all done. Next I took it for a drive and was absolutely amazed at the power increase right away. I only set it to regular fuel and have not messed with the other settings yet but I am getting bigger tires this weekend and will update more. I plan on filling up with premium next and seeing how much more power i get. As far as gas mileage I have not had it long enough to determine. In my opinion this was an expensive product worth every penny.

installed on Ford 5.4L f350, manual tranny, flatbed welding rig.Recalibrated speedo, tire size, rev limiters, reg fuel program was easy to install. No issues at all, just follow onscreen promps. Performance wise wasnt too impressed on day one. Day 2 drove to work around 75 miles and noticed at normal highway speed 70 mph the tach was averaging around 500 rpm less. So it did make a difference. This review is only day 2, but over 150 miles of highway driving.

Did not work on my 2000 Excursion XLT 6.8 gas. Jay at customer support was no help and was kind of rude and short with me. I would not recommend even trying this product as it is quite cheaply made. First you have to have your own adapter for the power cord and for the cost of this flimsy unit it should have came with it. As I stated this unit is very cheaply made and as soon as I pulled it out of its box the sticker on front that identifies the company fell off. I then noticed immediately how light weight and flimsy it is. Do yourself a favor and find another solution as I am going to do.

Way worth the money. Follow instructions fully. Be patient. Upload software to computer or laptop. Upgrade the program parameters as instructed if your first attempt at programming is unsuccessful. Software provided is super user friendly and easy to use. Upgrading/updating tuner is also quick and easy via internet. Only feature i am not totally satisfied with is that when selecting any top speed above the stock 107 or the next higher 116mph the tuner will not allow anything but the "premium" fuel option. So if you wish to max out the top speed governor you cannot run regular fuel, like, at all. It really needs to be ethanol free and in the neighborhood of 96-100 octane or it pings like a son of a bitch. All other features work well and as described and is very noticable improvement in felt mid range power, shift firmness, shift points and converter lockup. Can adjust cooling fans and adjust for performance modifications like intake and exhaust. Whith a very moderate tune on my unmodified Merc and a pcm reset i experianced a real jump in long distance gas mileage aswell. Very neat device. I would recommend to anyone who has mildly moded crown vic merc marquis or maurader and is looking for that edge or just wants to outrun an interceptor, this little handheld does it all and retains the stock parameters if you need to take it to the dealer for repair, just plug in and rewrite. Initial tune when changing from stock takes about 40 minutes. Does not throw codes or a check engine light. And the top speed limit that is available for my bodystyle is insane, and most likely beyond what the mechanical limits of an unmodified car are capable of. Be careful. Tires, torque converter, and driveshaft protection are a must over 120mph.
